What I claim as my invention, and desire to secure by Letters Patent oi the United States, is as follows:

1. In an expansible ring adapted to the support of a lamp or similar, article, the combination of overlapping ends, a longitudinal slot in the outer of said ends, said slot being widened at its inner end, and a projecting lug on the inner of said overlapping ends, said lug being formed with a body portion adapted to engage with the widened portion of said slot, and a neck adapted to pass through the body of said slot, substantially as described.
